Norway builds world's longest, deepest subsea tunnel

By PulseAugur Editorial · [1 sources] ·

Norway is constructing the Rogfast tunnel, which will be the world's longest and deepest subsea road tunnel upon completion. This ambitious engineering project extends 26.7 kilometers and reaches a depth of 390 meters below the North Sea. The construction utilizes the drill-and-blast method, a technique that involves significant logistical challenges and the use of explosives to excavate the tunnel through complex Norwegian geology. The project has garnered international attention, with representatives from countries like Japan, Spain, and the US visiting to learn from Norway's expertise in subsea tunnel construction. AI

    Inside the world’s deepest and longest subsea road tunnel

    It’s cold, it’s very, very noisy, and—if I can be quite honest with you—I’m not feeling super relaxed. I’m currently around 300 meters, or 1,000 feet, beneath the North Sea, in a dark, dank cave. It smells weird. And I am increasingly aware of the pressure from millions of tons o…
